Description

Technical Field

[0001] The present invention relates to the technical field of flexible wire winding devices, and in particular to a flexible wire winding device and a winding method. Background Art

[0002] In motors, power tools and other equipment, carbon brushes are key components for achieving current conduction. Carbon brushes ensure stable current transmission and normal operation of equipment by keeping in close contact with rotating parts (such as commutators or slip rings). In the structure of the carbon brush, multiple flexible copper wires for conduction are connected to its bottom. These flexible copper wires play a vital role when the carbon brush is installed in the equipment tool.

[0003] At present, there are significant technical defects in the process of installing the carbon brush into the tool: first, the flexible copper wire at the bottom of the carbon brush needs to be straightened for subsequent insertion into the tool. However, the existing operation method mainly relies on manual straightening of the flexible copper wire, and then manual insertion into the tool. This purely manual operation method has many disadvantages. On the one hand, the efficiency of manual operation is extremely low, which greatly limits the improvement of production efficiency and is difficult to meet the needs of large-scale industrial production; on the other hand, manual straightening cannot guarantee that the straightened flexible copper wire has a stable and appropriate hardness.

Therefore, the existing carbon brush installation method needs to be improved urgently, and a new technical solution is needed to improve the carbon brush installation efficiency and ensure the quality of straightening the flexible copper wire, thereby improving the production quality and performance of the overall equipment.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] Embodiment 1: refer to Figure 1 to Fig. 9A flexible wire straightening device comprises a base 1, on which a positioning and loading component 2 is fixedly connected, and a plurality of carbon brushes are temporarily stored on the positioning and loading component 2. A torsion component 4 for twisting the flexible wire at the bottom of the carbon brush into a strand is movably connected at the bottom of the positioning and loading component 2 based on a first sliding lifting component 3. The torsion component 4 is driven to slide and lift in the horizontal and vertical directions by the first sliding lifting component 3. A carbon brush clamping component 6 for clamping the carbon brush to realize loading and unloading and a flexible wire straightening component 7 for straightening the flexible wire twisted into a strand are movably connected at the top of the positioning and loading component 2 based on a second sliding lifting component 5. The carbon brush clamping component 6 is driven by the second sliding lifting component 5 to realize conveying the carbon brush from the material tray to the positioning and loading component 2, and the twisted carbon brush is conveyed from the positioning and loading component 2 to the assembly station of the workpiece, and the flexible wire twisted into a strand at the bottom of the carbon brush is straightened by the flexible wire straightening component 7 for easy installation on the workpiece.

[0021] refer to Figures 2 to 3 Specifically, the positioning and loading assembly 2 includes a loading seat 22 symmetrically slidably connected to the base 1 based on a slide rail 21 and a sliding cylinder 23 symmetrically fixedly connected to the base 1 for driving the loading seat 22 to slide. A plurality of step positioning grooves 24 matching the shape of the carbon brush are evenly spaced on the loading seat 22 along a direction perpendicular to the sliding direction. The step positioning grooves 24 on the two loading seats 22 are combined to form a positioning and fixing hole for realizing the positioning and fixing of the carbon brush. The loading seats 22 are driven to merge by the sliding cylinder 23 so that the step positioning grooves 24 are merged into a positioning and fixing hole, thereby realizing the positioning and fixing of the carbon brush. On one side of the loading seat 22 away from the step positioning grooves 24, there are evenly spaced and fixedly connected corresponding to the step positioning grooves 24 to realize the detection of the carbon brush. The laser detection sensor 25 emits a laser to detect whether the carbon brush is in place, thereby avoiding the shortage of carbon brushes during subsequent automatic installation and affecting the assembly process of the workpiece.

[0022] refer to Figures 4 to 5Specifically, the first sliding lifting assembly 3 includes a first horizontal screw slide 31 fixedly connected to the base 1 in the horizontal direction and a first vertical lifting slide 32 fixedly connected to the sliding end of the first horizontal screw slide 31 in the vertical direction. The torsion assembly 4 includes a torsion motor 41 fixedly connected to the sliding end of the first vertical lifting slide 32 in the vertical direction and a clamping cylinder 42 fixedly connected to the torsion motor 41. A torsion clamp 43 for clamping the flexible wire is symmetrically arranged at the clamping end of the clamping cylinder 42. The torsion assembly 4 drives the torsion clamp 43 to clamp the flexible wire at the bottom of the carbon brush through the clamping cylinder 42 and drives the clamping cylinder 42 to rotate through the torsion motor 41, so as to twist the flexible wire at the bottom of the carbon brush into a strand. During the torsion process, the first vertical lifting slide 32 drives the torsion assembly 4 to descend as a whole. The torsion clamp 43 includes a clamping base 431 and a gathering groove 432 which is opened in the clamping base 431 along the vertical direction and is used to gather the flexible wire at the bottom of the carbon brush. A clamping groove 433 for positioning and clamping the bottom of the carbon brush is opened at the top of the clamping base 431. The clamping groove 433 is connected to the gathering groove 432 and the gathering groove 432 gradually increases in diameter from top to bottom. A torsion block 435 is connected to the clamping groove 433 based on spring sliding. A torsion hole 436 is opened in the center of the torsion block 435, and a plurality of screw holes are opened on the side wall of the torsion hole 436. The twisting hole 436 is provided with a gathering hole 437 for gathering the flexible wire at one end near the gathering groove 432, and the twisting clamp 43 includes a clamping base 431 and a gathering groove 432 with a diameter gradually increasing from top to bottom in the clamping base 431 along the vertical direction, and a clamping groove 433 for positioning and clamping the bottom of the carbon brush is provided at the top of the clamping base 431, and a twisting block 435 is provided in the clamping groove 433 based on a spring. When twisting the wire, the bottom of the carbon brush is clamped in the clamping groove 433, and the spring is compressed to make the twisting The block 435 is retracted into the clamping base 431, and the flexible wire at the bottom of the carbon brush is gathered in the gathering groove 432. Then, the first vertical lifting slide 32 of the first sliding lifting assembly 3 drives the clamping electric cylinder 42 and the twisting clamp 43 to descend so that the bottom of the carbon brush is separated from the clamping groove 433. The spring drives the twisting block 435 to return so that the flexible wire at the bottom of the carbon brush is gathered into the twisting hole 436. Then, the twisting motor 41 drives the twisting clamp 43 to rotate, and at the same time, the first vertical lifting slide 32 drives the twisting clamp 43 to descend so that the flexible wire is twisted into a strand. By utilizing the fact that the flexible wire is more dispersed as it is farther away from the carbon brush, the flexible wire is gathered into the clamping groove 433 and the gathering groove 432, the possibility of some flexible wires being unable to be twisted into a strand is reduced, ensuring that the twisted flexible copper wire has stable and appropriate hardness, and by providing a plurality of spiral grooves 438 on the side wall of the torsion hole 436 to assist in twisting the wire. At the same time, by providing a gathering hole 437 at one end of the torsion hole 436 close to the gathering groove 432, the gathering hole 437 can prevent the dispersed flexible wires from breaking during the gathering process.

[0023] refer to Figures 6 to 9 Specifically, the second sliding lifting assembly 5 includes a second horizontal screw slide 51 fixedly connected to the base 1 along the horizontal direction and a second vertical lifting slide 52 fixedly connected to the sliding end of the second horizontal screw slide 51 along the vertical direction, and a sliding seat 53 is fixedly connected to the sliding end of the second vertical lifting slide 52. The carbon brush clamping assembly 6 includes a first lifting cylinder 61 fixedly connected to the sliding seat 53 along the vertical direction and a first clamping cylinder 62 and a second clamping cylinder 63 respectively fixedly connected to the telescopic ends of the first lifting cylinder 61 in parallel, and the clamping ends of the first clamping cylinder 62 and the second clamping cylinder 63 are fixedly connected with a clamping block 64 for clamping the carbon brush. A locating groove 65 for locating and accommodating the carbon brush is provided in the clamping block 64. The first clamping cylinder 62 and the second clamping cylinder 63 respectively drive the corresponding clamping block 64 to clamp the carbon brush so that the carbon brush is positioned and clamped in the locating groove 65. Two clamping cylinders are provided so that the number of carbon brushes clamped at a single time can be flexibly adjusted. The flexible wire straightening component 7 includes a second lifting cylinder 71 fixedly connected to the sliding seat 53 along the vertical direction and a third clamping cylinder 72 fixedly connected to the telescopic end of the second lifting cylinder 71. A clamping block 73 for holding the bottom area of ​​the twisted flexible wire and pulling the flexible wire downward is fixedly connected to the clamping end of the third clamping cylinder 72. The clamping block 73 includes a clamping base 731 and a plurality of clamping plates 732 evenly spaced and fixedly connected to the clamping end of the clamping base 731 along the vertical direction. The clamping plate 732 is provided with at least two V-shaped V-shaped positioning grooves 733 for positioning the twisted flexible wire. The clamping plates 732 of the two clamping blocks 73 are staggered, and when the V-shaped positioning grooves 733 are combined, a clamping groove 734 for clamping the flexible wire is formed. When clamping, the clamping plates 732 of the two clamping blocks 73 are staggered, and the V-shaped positioning grooves 733 are combined to form a clamping groove 734 for clamping the flexible wire. 34 Thus, the flexible wire twisted into a strand is positioned. When installing, the flexible wire straightening assembly 7 first clamps the end of the flexible wire twisted into a strand and pulls the flexible wire downward to make the flexible wire as a whole complete the initial straightening. Then, it is released and moves upward to clamp the non-end area of ​​the bottom area of ​​the flexible wire and pull the flexible wire downward to complete the straightening again. Since there is a small distance between the bottom of the flexible wire and the clamping position, this section of the flexible wire can ensure high strength and is easy to insert into the workpiece for assembly, avoiding the need for manual twisting and straightening and manual installation. The two straightenings improve the straightening effect. In this embodiment, the clamping position of the clamping block 73 is between 4-10mm and preferably 4mm away from the bottom of the flexible wire twisted into a strand. While achieving positioning, it can also ensure that the flexible core wire protruding from the bottom of the clamping block 73 has sufficient strength to be inserted into the workpiece for positioning.
